355nm DPSS Laser With Excellent Beam Quality And Perfect Spot Characteristics
1. STJ Lark-Series 355nm DPSS Lasers
STJ Lark-Series Lasers Includes UV and green light, it adopts a thermal method combining conduction heat dissipation and air convection heat dissipation. The pulse width is narrower, the repetition frequency is higher, the beam quality is high, and the spot roundness is high. In terms of structural design, it is smaller in size, lighter in weight and more beautiful in appearance. In the electronic control design, strong anti-electromagnetic interference capability, high thermal management efficiency, user-friendly GUI interface.

2. STJ Seal-Series 355nm DPSS Lasers
The STJ Seal-Series Lasers includes both UV and green lasers with excellent beam quality and perfect spot characteristics. The whole machine adopts integrated structure design, and the optical path and external drive circuit are integrated, which makes the product have strong anti-interference ability. Optimize and upgrade the fully sealed structure to prevent external dust. At the same time, the isolation of external water molecules make the machine have strong resistance of humidity, making the SEAL series adaptable to harsher industrial environments. In addition, a self-cleaning system in the cavity allows longer lifetime of the machine.
